Must be mistaken about no frills cpu i thought you mentioned it. When you flash rom again install only "musti have apps" for me they are : whats app,facebook, greenify,adaway,instagram,wakelockdetector,youtube ,tapatalk.All others i install just for fun not really usong them.To fix problem with google playstore installing all that apps just uncheck "backup and restore apps" and you will be fine i dont use it at all since i lije to do install what i need manually.You will find that option in setting under Personal just below "language and keyboard" .
